Thanks for your feedback!
Can you please test again?
I added WebGL2 backend as separate binary selected during page loading if browser does not support WebGPU.
I left out WebGL rendering backend to shave off few megabytes but might have jumped the gun on WebGPU support.
The better choice clearly was offering both :)
Would you mind sharing which browser you use?
(WebGPU is getting really nice support finally - https://caniuse.com/webgpu - not _full_ coverage yet but getting quite prominent)
